Reference
Description
The ST72521xx-Auto Flash and ROM devices are members of the ST7 microcontroller
family designed for mid-range automotive applications running from 3.8 to 5.5V.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced
instruction set and are available with Flash or ROM program memory. The ST7 family
architecture offers both power and flexibility to software developers, enabling the design of
highly efficient and compact application code.
The on-chip peripherals include an A/D converter, a PWM autoreload timer, two general
purpose timers, I
For power economy, the microcontroller can switch dynamically into Wait, Slow, Active Halt
or Halt mode when the application is in idle or standby state.
